Python: eliminar archivos antiguos

I'm somewhat new to python and have been trying to figure this out on my own but only getting bits and pieces so far. Basically i'm looking for a script that will recursively search a directory and it's sub-directories and delete files that are at least 24 hours old but not alter the directories. Any advice or examples are greatly appreciated.

What have you attempted so far and what does it do wrong? -

Let's see the bits and pieces, perhaps we can help glue the together? -

You can't delete files from a directory without altering the directory. -

Esto usa el os.walk method to recursively search a directory. For each file, it checks the modified date with os.path.getmtime and compares that with (the current time). datetime.timedelta is constructed to create a timedelta of 24 hours.

It searches the directory os.path.curdir which is the current directory when the script is invoked. You can set dir_to_search to something else, e.g. a parameter to the script.

import os
import datetime

dir_to_search = os.path.curdir
for dirpath, dirnames, filenames in os.walk(dir_to_search):
   for file in filenames:
      curpath = os.path.join(dirpath, file)
      file_modified = datetime.datetime.fromtimestamp(os.path.getmtime(curpath))
      if - file_modified > datetime.timedelta(hours=24):

how can I modify this when I want to delete the old files and save the new one even if it was generated a minute ago. - ak3191

If you need it to check all files in all directories recursively, something like this ought to do:

import os, time

path = "/path/to/folder"
def flushdir(dir):
    now = time.time()
    for f in os.listdir(dir):
        fullpath = os.path.join(dir, f)
        if os.stat(fullpath).st_mtime < (now - 86400):
            if os.path.isfile(fullpath):
            elif os.path.isdir(fullpath):
